Try the logic

Paint a small quilt patch.

A five-by-five sample of Coverlet’s Patchwork logic. Every number names the area of one rectangle. Make a complete partition, then take the daily ritual to the app.

Sample Patchwork

Choose a clue, then paint its rectangle.

The areas are 6, 4, 5, and 10. Together they cover every square exactly once.

Choose the 6, then paint the six cells that belong to it.

Keep the result

Eight techniques. A new board in each every day.

Coverlet expands the rectangle idea into eight distinct logic languages, then turns every finished solve into a block in a private quilt.
